Over the years I have written several times similarly to this article. There are all kinds of special situations which are very important to the individuals who could be affected by these other than ordinary conditions. But the idea that the general case does not present a dominant strategy seems strange to me. It is insurance, at a cheap rate, and with the worlds most secure insurance company. Nevertheless, I am sure that these threads will continue to show up, and that many people who have no immediate need for the money, are not in a special category, and who are not deathly ill, will continue ti take SS at 62. One thing that is very often given inadequate weight is the prevailing level of interest rates on long term TIPS.
It is just something about how the human brain weighs outcomes and information. If there is a general idea to be gathered from this, I think it is that we tend to overweight dramatic or available but far from determinative factors. As Bayesians emphasize, the base case should carry a heavy weight.
